Answer:

The answer in the procedure

Step-by-step explanation:

Let

x----> the first number

y----> the second number

we know that

$\frac{x}{y}=\frac{3}{4}$

$y=\frac{4}{3}x$ -----> equation A

$x+y=35$ ----> equation B

substitute equation A in equation B

$x+\frac{4}{3}x=35$

$\frac{3x+4x}{3}=35$

$\frac{7}{3}x=35$

$x=35*3/7=15$

$y=35-15=20$

Jace is a songwriter who collects royalties in his songs whenever they are played in a commercial or a movie. Jace will earn $50

VashaNatasha [74]

Jace's song were played on 8 commercials and 2 movies

<h3>Further explanation</h3>

Simultaneous Linear Equations could be solved by using several methods such as :

<em>Elimination Method</em>
<em>Substitution Method</em>
<em>Graph Method</em>

If we have two linear equations with 2 variables x and y , then we need to find the value of x and y that satisfying the two equations simultaneously.

Let us tackle the problem!

<em>Number of Commercials = C</em>

<em>Number of Movies = M</em>

$\texttt{ }$

<em>Jaces songs were played on 6 more commercials than movies.</em>

$\boxed{C = 6 + M}$ → <em>Equation 1</em>

$\texttt{ }$

<em>Jace will earn $50 every time one of his songs is played in a commercial and he will earn $140 every time one of his songs is played in a movie.</em>

<em>His total earnings in the royalties from all commercials and movies was $680.</em>

$\boxed{50C + 140M = 680}$ → <em>Equation 2</em>
